We report a case of emergency caesarean section due to bleeding from placenta praevia under general anesthesia in a patient with asthma. General anesthesia was induced by propofol 150 mg and suxamethonium 80 mg, and operation was started immediately after tracheal intubation under cricoid cartilage pressure. ⋯ Although anesthetic maintenance was carried out by oxygen-nitrous oxide-isoflurane after delivery, no asthmatic attack was seen throughout the operation. Anesthetic induction by propofol for emergency caesarean section might be safe and useful in a patient with asthma with little effects to neonates.

We examined the influence of the bolus injection rate of propofol on the cardiovascular depression and injection pain. Fifty-one patients of ASA grade 1 or 2 were randomly allocated to two groups. After premedication with midazolam 0.06 mg.kg-1 and atropine 0.006 mg.kg-1 i.m., propofol 2 mg.kg-1 was injected to a forearm vein at a rate of 800 ml.hr-1 in Group A or 1 ml.s-1 in Group B. ⋯ The induction time was significantly shorter in Group B than in Group A (40 vs. 73 sec: P < 0.01). There were no significant differences between the two injection rates in peak reductions in systolic and diastolic blood pressure and heart rate. In conclusion, rapid injection of propofol was effective to shorten the induction time without any adverse effects.
